oI'LiNG DEVICE.

Application filed )ctober 6, 1924. Serial No. 741,972.

Ford motors which deliver oil to the crank case through the breather tube. Heretofore.such auxiliary devices have delivered oil 'directlyv into a breather tube at or near its inlet with ther result that part of the y oil has 1been blown out of the tube by blasts of air caused by the 'action of the motor pistons, tobe spattered over the outside of the motor. This blowing out has been lessened to some extent by .the provision of gauze screen to cover the tubes, but this protection at its best is inadequate. Y

The present invention has for one of vits objects to provide a novel and improved oiling device of the character mentioned adapted to deliver oil at a point well within `a breather tube and far enough below the breather ,tube inlet to preclude the possibility of the blowing out of'said inlet of any of the oil.

Another object of the 'invention is to provide an oiling device as just stated wherein the flow of oil through the device can be visible.

And yet another and more specific object of the invention is to provide an oiling 'def vice as stated in the two paragraphs just preceding, whereinV Aprovision ismade for creating a head of oil at the location where the oil enters a breather tube from the improved oiling device, the head of Oil being adapted to forni a seal in an open conduit of the device, which conduit is designed'to allow the flow of oil to be visible pa'st the inlet of sai-d breather tube, whereby the blowing of air upwardly through said conduit is prevented. v

lith the above and otherv objects in view, the invention comprises the construction, arrangement and combination of parts as now lo be fully described and as hereinafter to be specifically claimed, it being understood that the disclosure herein is merely illus trative and meant in no way in a limiting sense, changes in details of construction and arrangement of parts being permissible s0 long as within the spirit of the invention and the scope of the appended claims.

In the accompanying drawing forming a rpart of this specification,

Fig. 1 is af side elevational view of anlaV automobile engine having an oiling device in which the yfeaturcsof l the invention are incorporated j y Fig. 2 is a vertical, longitudinal, centralsectional view, on an enlargedscale, of the improved oiling device, showing` the same applied to a breather tube; c Y

Fig. 3 is a top plan view of the oiling device and breather tube of Fig. 2, withl breather tube cap orcover removed; and i Fig. i is a sectional view, ,corresponding with the showing of Fig. 2, of an oiling device of modified construction. v l In Figs. 1, 2 and 3 of the drawing I have disclosed a device having provision (u) for delivering oilto a point well vwithin a breather tube to preclude thepossibility of the blowing of oil out of said breather tube; (b) for rendering visible the flow of oil through the device; and (e) for creat-ing a head of oil atl the location where the oil enters the breather tube from the loiling device, toform a seal in an openconduit of` the device whereby the blowing of oil upwardly through the conduit of the device is prevented. In Fig. l of the drawing Ihave disclosed a novelv andmo'dified arrangement of conduit, which is not open'to t-he inlet of the breather tube or an extension piece therein, for similarly delivering oil well within a breather tube and far enoughaway from its inlet to prevent the blowing of oil out of said breather tube, the modified ar# rangement ordinarily not providing for visibility of flow of oil through thev conduit, but the flow being visible when said conduit is a transparentmember or is provided with a sight glass.

VVithrespec-t to Figs.A l to 3 of' thedraw ing, A10 denotes an automobileengine, 11the crank 'case thereof, l2' ay hollow shell or the like situated in usual or preferred manner above the fly wheel (not shown) for receiving oil from the transmission case as the ily wheel rotates, and 13 denotes an oil feed pipe leading from the shell 12 toward the breather tube 14.

Of the improved oiling device, 15 is a generally cylindrical extension piece adapted to fit into the breather tube as represented at 16, and 17 is an oil conduit, vpreferably arranged vertically in the extension piece and breather tube, which is held in place in Vthe extension piece 15 by a separator or spider' 18 provided with openings 19 for the free passage of air. The usual cap orcover, 2O for the breather tube is adapted rto fit 'upon the upper end or inlet 21 of the eXtension piece. Y

The oilfeedpipe 13 passes through openings 22 and 23 in the extension piece 15l and conduit 17, respectively, to deliver oil'at 24 within the conduit 17, the location 24being, as shown, not far from the upper en-d or inlet 21 of the extension piece.

` The conduit 17 is of somewhat greater diameter than is the feed pipe 13, and-the 'delivery end of the feed pipe is, naturally,

visiblepast the inlet of the breather tube when the cap or cover of the tube is removed. The lower end or delivery end 25 A,of the conduit 17 is preferably reduced in area, for two purposes: First, to collect the oil into a solid stream before itsdelivery to the breatherrtube at the location well within said breather ytube so that blasts of air,

caused'by alternate pressure and vacuum in the crank case dueto the action of the motor pistons, through the breather tube and around the conduit 17 will notl be sufficiently powerful to blow any of the oil out of the breather tube inlet; and, second, vto cause a partial stoppage of flow of oil through the conduit 17 and thus create a slight head of oil yat Ithe delivery end ofthe conduit to form an yoil seal and effectively prevent all portions of said blasts of air from blo-wing upwardly through said conduit.

With respect to Fig. 4, 'numeral 14 ldenotesthe breathertube, and 20 Irepresents the cap or cover thereof. The oil feed pipe 13 passes through an opening in a bushing 26 'threaded in the breather tube as at 27, not far from the breather tube inlet.l In the prese-nt form of the invention, the eX- tension` piece is omitted, and the oil feed pipe has a right-angle bend y28 situated desirably near the transverse center of the breather tube, to provide a` conduit '17 h'avf ing` a delivery end 25 situated with respect tothe 'breather tube as the delivery end 25 of the conduit 17 is situated. The flow of oil through the conduit 17 of the lfeed pipe 13" will be in a solid stream, ordinarily, and oil delivered to the breather tube from the conduit 17, well within the tube, will not be blown out vof l`the breather tubefiifilet.

Crfdinarily, the oilin-g `device :of Fig. l'4

willnot be provided with an arrangement whereby the oil flow-ing `through the conduit 17 can 'be-visible, but clearly, this iiowof ylivery end can be visible ery ofoil to-saidcrank case, an extension piece adapted to fit said breather tube, a conduit located in said extension piece and having a delivery end situated well within said breather tube at considerable distance from the inlet of said tube, 4and an oil feed pipe including a delivery end entering said conduit.

2. In combination with a crank case and la breather tube adapted to allow the delivery of oil= to said crank case, an extension piece adapted to fit said breather tube, a conduit located in said extension piece and having a delivery end of reduced area .situ-l ated well within said breather tube at considerable vdistance from the inlet of said tube, and an oil feed pipe :including a deliveryend entering said conduit.

3. In combination with a crank case and a-breather tube adapted to allow the delivery of-oil to said crank case, an extension Vpiece adapted to fit said breather tube, a conduit located in said extension piece and having 'a delivery end situated well within l sai-d breather tube at considerable distance from the inlet of said tube,and an oil feed pipe passing through said extension piece and including la delivery end entering said conduit, whereby oil passing from said depast'the inlet of said breather tube.

4. In ycombination with a crank case and a lbreather tube yadapted to allow the delivery of' oilfto sai-d crank case, 'an extension piece adapted to 'lit said 'breather tube, a conduitlocated in said extension piece and having a delivery end situated well within said breather tube at considerable distance from the inlet of said tube, a separato-r insuring thevposition of the conduit in the extension piece, and an oil feed pipe fitted n the `extension piece Van-d entering theconuit.
